Search Tools: Faceted Metadata Search and Browse
This article explains the concept of faceted metadata using examples of popular websites. "Metadata is information about information: more precisely, it's structured information about resources. This can be a single set of hierarchical subject labels, such as a Yahoo or Open Directory Project category. More often, the metadata has several facets: attributes in various orthogonal sets of categories. This is often stored in database record fields and tables, especially for product catalogs."
